  • Page 3 With the aim to develop a compact three-way product, the tradi- tional waveguide simply had insufficient space. Hence Genelec started to develop a new coaxial driver, which would combine Midrange Frequency / High Frequency (MF/HF) waveguide for proper directivity control. The basic solutions were developed in the late 90’s to prototype levels.
  • Page 4 Recently Pioneer/TAD has developed a coaxial MF/HF driver using Beryllium diaphragms. The New Genelec MDC™ Solution Figure 4: On axis frequency response of the Genelec MDC driver. The frequency response shown is from 2 kHz to 20 Typical to all current coaxial designs is somewhat ragged fre- kHz.

    To summarize, the main novelties of Genelec combined DCW™ and MDC™ designs are: The Genelec Iso-Pod™ vibration isolation stand is a part of the 8260A as well. The Iso-Pod™ stops the propagation of whole • Diffraction-free joint between tweeter and midrange dia- enclosure vibration to the surrounding structures.
